Like many things in this world, there are a multitude of problematic situations that halts one’s objectives, and most of the time, there is no way to maneuver around that problem. For example, getting to Mars. Going to Mars is something that is possible, considering the fact that humans have been there a couple of times already, like the Mariner 4 or the Curiosity Rover (Cain 1). Although this is true, there are still plenty of problems with sending people to Mars. Some of these problems include how they are going to come back to Earth, or if they can survive Mars, at the least survive the ridiculously long ride to Mars (Cain 1). On the other hand, they have problems that technology can solve, like where they are supposed to get our Oxygen …show more content…
To sum it all up, the space craft cannot carry enough fuel to go to and back from Mars. The one way that this problem can be solved is simply to use a configuration in which not that much fuel is used. So for that to happen, there would be a second problem, which is time. If they were to try to conserve fuel, they would end up taking more than 300 days to get to Mars itself (Cain 1). Even if it was possible to carry enough fuel to go to and back from Mars, the weight would be way too high, to the point where the space craft can’t even takeoff (Strauss …show more content…
Also, people need food to survive which means it would be required to have a certain amount of food for the duration and thus increase the weight of the space craft. That just defeats the purpose of increasing the duration of the journey to save fuel. Another factor is the question of why the duration is so long. “When you consider the fact that Mars is only 55 million km away, and the spacecraft are travelling in excess of 20,000 km/hour, you would expect the spacecraft to make the journey in about 115 days” (Cain 1). The thing to take into consideration when creating the flight plan is that Mars will always be moving and if the plan was to just go towards Mars in a straight line, our target would not be there anymore (Cain 1). To ultimately reach Mars without missing it is using the technique: Orbit Transfer (Stern 1, Unger 1). To explain it simply, the space craft move the space craft from Earth’s orbit to Mars’s orbit. Other than the problems that are present before getting on Mars, there are plenty of problems and factors that must be taken into consideration when the space craft lands on Mars. As mentioned before, food is one of the major factors that is extremely important in this journey. Fortunately, there’s already a plan in case we do go to Mars, and that’s to bring
Not only will rockets be constructed differently, they also don’t have to carry food or water -- reducing weight and cost as mentioned earlier. NASA has estimated that sending a manned mission to Mars would cost at minimum billions of dollars (Mann - Humans VS Robots, 11). Rather than sending a manned mission, multiple robotic missions could be sent in place allowing for even faster data collection. For quite some time space funding has been a constant; from 2012 to about 2017 NASA was projected to receive around 17.7 billion per year in funding which makes robotic space exploration a much more fiscal solution (Mann - Almost Being There, 13). Cost has been one of the largest if not the largest problem with space travel, as discussed by the Space Panel from TAM 2011 in Las
A manned mission to mars is too dangerous. First, it's cold. For instance, the average temperature is -61 degrees Fahrenheit. Since, it’s too cold it’s dangerous. Second, earth’s gravity harms the human body. For example, bones and muscles get weaker and the body produces less blood. Since, your bones and muscles get weaker and the body produces less blood this shows you that a manned mission to mars it too dangerous. Third, traveling is dangerous. For instance, traveling in a spaceship because minimeterorites can kill you. Since, minimeterorites can kill you this tells you that it's way too dangerous. In conclusion, a manned
Perhaps when my children are my age, a trip to Mars or even to the moon will be something that the average citizen can look forward to. After our nation has spent trillions on learning how to get into space, it is time to pass the torch. It may very well be that only through privatization, competition and collaboration, that the price tag of orbiting the Earth will finally become reasonable. Until then I can only close my eyes and picture the sign on our first extra terrestrial colony. It could very well read, “Welcome to Mars Colony, Sponsored by PNC
Colonizing Mars, it seems like a distant achievement. Some say impossible, some say it will happen soon. Since Elon Musk has entered this field of exploration colonization of Mars has seemed even more plausible. Still, problems have surfaced to make this much more difficult than it has to be. This makes some believe this to be impossible or unlikely for the time. Despite what side you are on we can both agree that we want to advance in space exploration.
The final major concern is the cost. Consequently, he estimated cost is over $100 billion. While this is very expensive, it will be a long-term investment, and it will later benefit humans by gaining the possibility of colonizing Mars when future problems
It is hard to get to Mars and it is even harder to land on Mars, thus Spirit and Opportunity had to overcome numerous challenges in order to land on Mars and to carry out their missions. These two rovers were required to fly through approximately 483 million kilometers of deep space and a very precise landing spot had to be targeted (Jet Propulsion Laboratory 2011). Although their flight paths can be adjusted along the way, however, a minor trajectory mistake can lead to a big detour and/or complete missing of the planet. Besides that, the environment of space is full of hazards that are addressed as “single event upsets”, as when a stray particle of energy goes through a chip in the ...

...or obstacles to our survival as a species.” Climbing our way out of this situation will not be easy, it will require an enormous amount of work. It will require a society to act for the welfare of the future, not just immediate needs.
There are also military uses for aerospace planes, just a few of these extremely fast and efficient vehicles could replace fleets of regular bombers (80). Another cost-effective option for space travel is the solar sail. Solar sails work because solar photons have pressure that pushes the sail away from the sun (100). A spacecraft with a solar sail could reach Mars in the same amount of time it would take a rocket, so it is a cheap, renewable method of travel (100). This is exactly what we need to make it to Mars.
Problems included the effects of zero gravity, how to make a sustainable food source in space with a limited supply of water, how to stay fit, & how to keep food from spoiling in space for the long-term trip from Earth to Mars and back.
Mars is an interesting topic for me, it represents an upcoming change in human engineering- a change in our thinking. Sitting in my blue chair, I ask myself questions. What do we do with our little red planet? Do we colonize it? Make it like our Earth? Or do we ignore it,...
NAME- Vedika Sakhardande COUNTRY- France COMMITTEE- Futuristic Mars Committee Humans are known for adapting, that is the reason they been able to survive through all the changes earth has faced in the past millennia. But now the human race is on the brink of extinction as the world now is nothing more than a toxic wasteland. Several factors such as pollution, deforestation, ozone depletion, green house effect etc, have piece by piece torn apart mother earth. The atmosphere is ruined, the air fatal to breathe, climate changes have occurred which have changed the fate of mankind, floods have occurred due to melting of polar ice caps, crops have failed and resources have been depleted.
The Mars mission would be difficult to accomplish because humans would have to spend billions of dollars on the venture.
Mars is one of the most mysterious planet in our solar system. Scientists haven’t figured everything out about Mars, but they do know important facts. The fictional story “Follow the Water”, by Jennifer L. Holm, and the non-fiction “What Would It Take to Live Here”, by Mackenzie Carro, are both two very informational stories about mars. Scientists believe there is a way that living things could live on mars, but there are some factors getting in the way of them being able to know for sure if this theory could happen in the future.
Humans can expect to face some major challenges on an expedition to Mars. It has been proven that humanity can travel in space for over two years. Cumulatively, Sergei Constantinovich Krikalev, a Russian cosmonaut, has spent over eight-hundred and three days in Earth orbit (Lyndon B. Johnson Space Center, 2005). The expedition to Mars would require the crew to endure a six month journey to the planet, a year of living on the planet, and a six months journey back to Earth. Russian cosmonaut, Valery V. Polyakoz, clocking in at four-hundred and thirty-eight days for just one stay in Earth orbit, shows humanity is capable of a twelve month round trip to Mars (Schwirtz, 2009). Earth's orbit has provided some benefits to space exploration, like the magnetic field from cosmic radiation, and the proximity to Earth if an emergency were to arise (Jones, 2009). The further humans travel away from Earth the greater the risks become. The major risks to human health on a flight to Mars, living on Mars, and returning to Earth are: radiation exposure, biological problems induced by weightlessness, spacecraft malfunctions, and psychological problems brought on by isolation.
